Well, I think everyone has always agreed that the most accurate way to check azimuth is with test tones and measurements of output signal level; and we know know that perfectly vertical may not produce most equal crosstalk because of possible differences between the two sides of the generator. But in terms of comparison to all these other produced, produced in vast scale on computer controlled assembly lines, it's kind of apples to oranges. You get a high end cartridge and the spec is going to be 0.5 dB channel balance, 30 dB channel separation. But you still have to install it and set it up correctly. You know, you're car engine may be up to spec, but if you don't but the right timing belt in there, it's not going to work right; you watch may be accurate, but if you don't set the right time, it's not going to tell you the right time. The cart may be up to spec, but when you install it you do basic setup for overhang, parallelness, VTF, VTA and azimuth, and to get it just so it may need a little bit of this and a little bit of that. It never occurred to me that azimuth alignment could be such a contentious issue.
